To all whom it may concern:

Be it known that I, ALoNzo GFMATHER,

.a citizen of theUnited States residing at 'Glncago, in the county of Cook and State of Illinois, have 'invented a new and useful Combined Metallic Draft-Sill and Body- Bolster, of which the following is a specificatlon.

My invention relates to draft sills and body bolsters for cars and particularly for freight cars known as long draft timber construction,,and the objects of my improvements are first, to, make the draft sills and body bolsters of removable sectionsor parts; second, to make the draft sillsand bolster of metal and arrange the draft sills to have them replace the usual wood draft sills :third, to make the draft sills fit either wood or metallic sub-sills or beams; fourth, to make a strong durable and GlllClGIlt construction and other features to become apparent from the description to'follow.

In the upkeep of freight cars it becomes necessary to renew different parts and there is an ever increasing tendency to replace parts made of wood with parts made of metal. In what is known to the art as long draft timber cars, the draft timbers extend substantially the entire length of the car, 6., beyond and between the upper and lower members of the iron body bolsters near each end of the car, andmy improved draft sillsare so arranged that they can be substituted in place oftheawooden draft timbers, passing between the upper and lower members of the iron body'bolster; and furthermore the ends of my improved draftsills are constructed so as to properly cooperate with either wooden draft timber sub-sills or metallic beams substituted inplace-thereof. By this means the wooden dra-ft'sillportion maybe substituted by the metallic construction or both the draft sills and the long subsills may be substituted by metallic construction. v 1

A further object of my improvement is to connect the draft sills to the body bolster so that it is very rigid and strong and so that the parts can be disconnected m'sections when necessary without removing the greater part of the under construction of the car.

To describe my invention so that others versed in the art to which it pertains can make and use the same, I have illustrated it on the accompanyingtwo sheets of drawings forming a part of this specification, and inwhich: r o

f Figure 1, is a plan view of the under constructionof a car having my invention ap plied thereto with the main center sills removedyFig. 2, is sectional view taken on line 2-2 of Fig. 1, but showing wood subsills instead of I-beams; Fig. 3, is a sectional view taken on line 3 8;of Fig. 1,- with parts in elevation; Figs. 4 and 5, are detail views showing a plan and a side elevat1onrespectlvely of the a king bolt or filler casting shown in'Figs. 1 and 3; Fig. 6, is a-detail 7 plan view ofione draft sill shownin Figs.

1, 2 and Figs..7, 8,.9'and10, are cro'ss sections taken onthe correspondingly num bered lines of Fig. 6, respectlvely, viewed in the direction indicated by the arrows, and

Fig. 11, is a plan view on a-small scale showmg the iron body bolsters near'each end of the car and the manner of their cooperation between the ends of the draft sills and the sub-sills of the car.

Similarr'eference characters refer to similar parts'throughout the several views.

The draft sills comprise two counterpart arms 12 betweenthe one end of Which the drawb-ar 13 and the usual draft gear mechanism is situated; the remainingends of the draft sills 12 are provided with twovextending'fiat bars 14. parallel and spaced apart sufliciently to straddle the web of an I-beam 15 as indicated by dotted lines in .Fig. 10.

The extremities of the fiat, bars Mare bent at right angles in opposite directions to form an abutment 16 against which the ends of the wood sub-sills 17 rest andthus carry the shock exerted at one end of the car to the other end of the car. It will be noted that the sub-sills 17 extend from the draft sills at one end of the car to the draft sills at theother end of the car as shown in .Fig. 11,110 matter if the sill lSfOlHlGCl of'wood or of an I beam. As viewed in said Fig 11, the sills 17 are shown as of wood and in Fig. 1, the sills are shown as -metal. Whenthe sills 17 are formed of I beams their ends are Patented s t. '30, 19 19.

The follower 'plates 20 are retained in position in the depressions I l9- by suitable bars 21 bolted tothe under} sideof each arm12i The usua'lvsprings 22 i' are interposedbetween thei'ollower plates 20, and the said plates 20 and springs 22 are confined within the yoke 23 and the end of 'thedrawbar 13 in the usual way. The arms '12 are located: directly under the main ear sills 24 and also extend underthe'endjsills -25and the dead Wood 26/ The deadwood 26 is preferably provided with the protecting channeliron 27' and the iron plate 28 to reinforce the same. The plate 28 rests against a shoulder or 'ofi'set 29 formed on the arms 12. The arms 12 are securely bolted to the sills 24 and'25 and also to the dead wood 26. To'form additional rigidity between the arms 12 and thesills 24, the arms '12 are provided with transverse ribs 30 which fit into cooperating IlOtCl16S'3l provided in the sills 24 as clearly shown in 1F igsl and 2.
